Start with the totals before you chase line items
Find the total card sales, total number of transactions and total fees for the month. Those three numbers give you the shape of the account before you get into the details. If the statement shows $100,000 in card sales and $3,100 in total fees, the rough effective rate for that month is 3.10%.
That number is useful, but it is not enough to decide whether the pricing is good or bad. A business with a lot of rewards cards, keyed transactions or small tickets can naturally land higher than another business. The effective rate tells you where to look. It does not tell you who is responsible for every dollar.

Interchange is usually the biggest piece
Interchange is paid through the card system to the card-issuing bank. The amount changes by card type, transaction method, business category and other factors. On an interchange-plus statement, you may see dozens of interchange categories. That can make the bill look worse than it is because the largest section is also the section your processor usually does not control.
A common mistake is asking a processor to “lower interchange.” In most normal merchant setups, the better question is what the processor is charging on top of interchange.
Interchange can still tell you useful things. If a surprising amount of volume is falling into more expensive categories, it may point to how transactions are being entered, how the account is configured or what kinds of cards customers use.
Card-network assessments are separate from processor markup
Visa, Mastercard, Discover and American Express charge network-level fees and assessments. They may appear as separate lines or get blended into another section depending on the processor. Like interchange, these costs are generally outside the processor's ordinary markup.
This matters because a quote that talks about a very low “rate” may only be talking about the processor's piece. If the quote does not show how interchange and network fees are handled, the headline rate can be almost meaningless.
Processor markup is where the pricing discussion usually gets interesting
Processor markup is the part added for the processing company and its partners. On interchange-plus pricing, it often appears as a percentage markup, a per-transaction charge, or both. For example, a statement might show interchange plus 0.30% and $0.10 per transaction.
That 0.30% matters more as card volume grows. On $100,000 in monthly card sales, 0.30% is $300 before the transaction fee is counted. A difference that looks tiny on paper can become real money over a year.
Some processors make this section easy to spot. Others spread markup across several lines. If there is one part of the statement worth slowing down for, this is it.
Monthly and incidental fees can add up quietly
Statements can include PCI fees, statement fees, gateway fees, batch fees, annual fees, monthly minimums, account fees and other charges. Some are legitimate costs for a service the business actually uses. Some are negotiable. Some have simply been sitting there for years because nobody has asked about them.
Do not assume every small fee needs to disappear. A useful review asks whether the fee belongs there, whether the amount is reasonable and whether removing it would affect something the business needs.
Use the effective rate as a checkpoint, not a verdict
To calculate a simple effective rate, divide total processing fees by total card sales. If fees were $2,850 on $90,000 in card sales, the effective rate was about 3.17%.
Compare that number across several months if you can. A single month can be distorted by annual fees, chargebacks, unusual card mix or seasonal sales. A pattern is more useful than one isolated number.
What deserves a closer look?
A statement is worth digging into when processor markup looks high for the account, recurring fees keep multiplying, pricing has crept up without a clear reason, or the business cannot explain what several charges are for. Another good reason is simply time. If nobody has reviewed the account in years, the current pricing may reflect an old negotiation that has never been revisited.
The goal is not to prove that every statement is bad. Sometimes the numbers are already competitive. A useful review should be able to say that too.
What Tenmile checks first on a statement
Before chasing individual line items, Tenmile starts with total card volume, total fees, transaction count and the processor's stated markup. Those numbers give the account some context. From there, the review separates interchange and network assessments from processor-controlled pricing and checks recurring fees that may have been added over time.
The point is not to find something wrong on every statement. It is to figure out which dollars are fixed by the card system and which dollars are actually worth discussing with the processor.
